The best know TV standards are NTSC/PAL/SECAM. but for decoding a frame that
information is not enough. There are several formats of the TV standards.
And not every TV decoder is able to handle every format. Also the every
combination is supported by the driver. There are currently 11 different
tv broadcast formats all aver the world.

The CCIR defines parameters needed for broadcasting the signal.
The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,...
The CCIR says not much about the colorsystem used !!!
And talking about a colorsystem says not to much about how it is broadcast.

The CCIR standards A,E,F are not used any more.

When you speak about NTSC, you usually mean the standard: CCIR - M using
the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada
and a few others.

When you talk about PAL, you usually mean: CCIR - B/G using the PAL
colorsystem which is used in many Countries.

When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem
which is used in France, and a few others.

There the other version of SECAM, CCIR - D/K is used in Bulgaria, China,
Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others.

Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly
used in PAL VCR's that are able to play back NTSC. PAL 60 seems to be the same
as NTSC 4.43 . The Datasheets also talk about NTSC 44, It seems as if it would
be the same as NTSC 4.43.
NTSC Combs seems to be a decoder mode where the decoder uses a comb filter
to split coma and luma instead of a Delay line.

But I did not defiantly find out what NTSC Comb is.
